Yes, purchasing alli is an investment (US $50 for the starter pack; US $60 for the refill). But you may not have to pay for it out of pocket. alli may be reimbursed as part of flexible spending account (FSA) plans just like any other FDA-approved OTC drug.
In September 2003, the IRS announced that over the counter (OTC) medicines are reimbursable using some health plan flexible spending accounts. Money put into these accounts is not taxed and can be used to pay for OTC medicines in addition to other uncovered medical expenses.
Until now, some guides to FSA programs have pointed out that weight loss supplements are not reimbursable. This continues to be true, but does not apply to alli, which is FDA approved.
Reminder: you should check with your plan administrator for eligibility requirements if you want to be reimbursed for alli with your remaining 2007 FSA account or when planning for 2008.
